Be it known that I, Mine, a citizen of the United States,- residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in a Delivery Mechanism for Embossing Machines, of which the lfollowing is a full,

clear, and exact description, reference being f had to the accompanying drawings.

This invention relatesto. mechanism -for delivering printingv strips from a forming machine therefor onto a suitable blanketl adapted to hold the same for printing. My

:delivery mechanism is designed to be mountedon and cooperate with an embossing yma-V chine adapted to emboss printing characters on strips of metal which are flanged'inwaidly at their edges and delivered by suitable rolls. My mechanism is correlated with suoli-embossing machine so thatitmay operate automatically to advance such elivered strip onto a suitably held blanket ,mounted about a drum and intermittently fed to bring a new line of strip holding means int-o registration with such delivery mechanism. Y An embossing machine with which my de- Alivery mechanism may cooperate is shown, described and claimed in the application of Clifton Chisholm, No.1535,311, filed Februaiy 9, 1922, and so much of such embossing machine as directly cooperates withmy wdelivery mechanism is shown in ythe present CAD ' l application.

Certain features of rthe present delivery mechanism are also shown and claimed in a prior application of mine, No.` 583,192, filed AAugust 21, 1922, which provides for the: lmanual delivery of embossed strips onto a` flat address plate. Certain other features ofV the present mechanism are shown and claimed in an application of Clifton AMy mechanism is an improvement on the Chisholm mechanism )ust mentioned, among other features in that it operates automatically both to move the strip onto the blanket andv to move the blanket for a new line.

It should also be notedA that the blanket shown herein com risinr a late havin` J .D

In. order that my delivery apparatus may be better understood ll will first' describe.

brieiiy the embossing machiner illustrated in Figs. 1 tov 5inclusive, though it is to be understood that my invention is not limited to. coaction with that particular type of embossingl machine.. Y i i' Theembossing machine shown comprises areciprooable die carrier 1.0, having indi-y vidually `movable male andA femalev dies 11, Y

a keyboard 12, and-suitable mechanism controlled-fl by the keyboard for 4positioning the die carrier andconsequent upon. suchl positioning a atoma'tically` 'plunging the selected dies toward eac-h other to embossf an intermediate strip 13y which isfed from a suitable reel 14l and hangedy atits edges by intermittently operated' rolls 15. Such flanged strippasses along: a supporting rail 16:'be-

' hind; a retaining rail 17, both extending through anv open longitudinal spacein the die carrier. .-rlhese rails are cutaway at thecentral portionA 18: where the selected `dies operate toV eiect the embossing.

To reciprocate the die. head of this Chisholm embossing machine there are .provided a pai-:r of? solenoids1201 operating on arcommon. core. barl 21 connected'by a link andlever 22=with the diehead, the solenoid on, either side beingy energized Whenever a key in the corresponding half of the key-` to actuatethe plunging` mechanism about'Y to;V be. described. After this Vplunger 30 passes over the key lever, the die carrier` is stopped by engaging the resilient abutment,

322andthenfthe plunger 30 descends to rest;

behind the. keyl lever, sov that the die carrier araised key lever.

Lsst/,Sii

becomes locked in a deiinite position with the dies corresponding to theactuated key in the central ory embossing position.

` The raising of the plunger/3Q swings a bale 3 5, which by means of'a linl' and a bell' crank 37 withdraws the rod 38 from a single=rotation clutch 4Q. This clutch, thus freed, clutches the continuously rotating Vmain. driving pulley 47 to the shaft 4l,

which carries a pair of crown cams, indicated at 42 in Fig. 2, which operate on the l' lower end of intermediately pivoted levers 43 and144., which act. to shove inwardly Silit-A able olungers 45. and 46, which engage the outer ends of theselect'ed female and male dies respectively, or the shearing dies 48- and149 shown in` Fig. 4.V Y

Following thev embossing operation the plunging mechanism returns; to normal. posi..- tion, spring fingers 50. on the diehead returnl the. dies, the.. key returns, the circuit, to the energized solenoid is opened and thecarrier is returned to normal position .under the in. fluence. of a compression spring on either side. of the. carrier, one of these spr-ings vbeing illustrated at 51 in Fig. 4. During theseretiirn operations. the, stripy is` fed to. ward the right. a distance of one character byv means of the rollsl.. AS Shown; one of these rolls carries a, ratchet 5,2 operated by a pawl 53 on a suitablev lever Connected by e link 54 with a rook arm on the rock shafti,

55, which also carries the die operating lever 43. Y y

The mechanism tor returning the. keyv levers,.shownin Fig. 4:, comprises a hook 6,() on the embossing lever 43, which on the re: n

turn or outward, stroke' engages the` upper endofa pivot-ed latch plate. 61, the lower` end oi which 'extends beneath; a; tooth 62 on When thislower end is. withdrawn thel keylever is freedv andthe lever is suitably. returned. v l

Figs. l1 and4 indicate, at 65 levers for: ClOS- ing the solenoid switches when a key is depressed. Eachv of these levers carries` a rod 66 ove-rhan-ging suitable upward extensions 67.on the rear portions ofthe key levers. Fig; 4. illustrates alsov suitable mechanism fornorrnally locking. the die head in Central position, comprising a central gib 70 on the diehead adapted to standbetween4 the upper ends of two levers 71 and 72 pivoted at 73j and each. carrying at; its forward enel a universal bar, 714,' (5, which extends over all of; the key levers in that half of the keyboard. The actuation ol any key thus releases. the -diecarrier before the, solenoidacts to move the .die Carrier. Y

Fig. 4 Villustrates also mechanism whereby theSvpaCe key may release the clutch with out releasing the. die head, resulting in feeding of the metal stripVV without embossing. Thus the space bar 80, Fig. 1, is` mounted on levers, one of which 81 carriesat its rear,

IQQ:

end a dog 82 which extends beneath the bell crank 37 connected to the clutch rod 38 heretofore mentioned. l/Vhen the space key is depressed the dog 82 is raised initiating the operation' of the clutch then the dog immediately Vpasses out of engagement Vwith the embossing levers 43 and 44 operate to plunge these dies toward each other. The die 49 has notches to receive the edges of the flanged strip, and the die 48 operates to' shear first through the corners` of the strip and then the body of the strip, thus cutting out a short section and leavingfree the embossed line strip indicated at 9 2 in Fig. 2.

It will be'seen from aninspection of Fig. 5'that the shearing. die 548 there shown is `of materially less height than the character dies'11. This is because in this embodiment each character die has three related faces (lower case, upper case, numerals and punctuation) controlled by a shift mechay nism. The shearing dies are positioned 'cor-vv respondingto the lowerv case characters on' the character dies. .It is accordingly desirable that whenever the shearingdie is about to be operated kthevshift mechanism be` auto-I matically operated to carry the die head to lowercase position, if it is not already in that position.

Mechanism for the above purpose is illustrated in Figsfl, 2 and 21, wherein 100 indicates a shift lever connected with the die head toraise it, the lever having twoarms, 99 connected to vertical slides, 98'carrying a horizontal rod, 97on whichthe die head travels. A101 and 102 are respectively slidable and fixed keys adapted to pushthe le- Vver 100 down a certain distance to shift the` die head one step, or twice that distance to shift it two steps, according to whether the stem 103 of the key 101 or the shorter abutment 104 limits the movement 'by strikingl against a stationaryv abutment 105. The key stem 103 is slidable through the lever so that the latter may continue to-descend when `the key 102 is pressed.

6,6.,The shiftkey is heldk ineither of the depressed positions by a toothed latch i 107 drawn toward it by .a spring 108. This specie mechanism is the invention of Clifton` Chisholm and will be covered by an applircation about to be filed by him. 1 f The position of the shift key lever 100 Figs. 1 and 21 indicates a shearing shown'in-Fig. 21 is the lower case positionf of the character dies and the active posi-'1 tion of the shearing dies.

Tol insure 4the die head being in that position when the shear` ing key is' operated, I attach a link 110 to the shearing' key lever and connect it to a rockjarm 111 on a rock shaft 112 which *l carries an arm 113 adapted to engage a shoulder 114 on a pivoted arm 115, theups per end of which has a fork and pin c onnection with vthe latch 107.- The result is that whenever the shearing key is depressedfy the latch 107 is swung forwardly, releasing the shift lever, and accordingly if that lever happens to be in either of its depressed positions this frees thedie head andfallows f it to drop by gravity to its normal ior lower case position.

Thef operation of the shearing key de-v scribed initiates l the operation of my' delivery mechanism which will nowbe described with reference rst-to-`F igs. 1, 2, 3, 5, 6, 18,

19 'and 20'.'

Onthe rockdshaft 112v above mentionedv in connection withy the shift key is an arm 120 connected by a link 121 with.l a lever- 122fpivoted at 123. The other end of' this lever carries a depending rod 124 whichhas f a vshoulder 125. When the shearing key isl depressed to `effect the shearing', the bar 124 is simply raised idly. Followinglthel shearing, however, on the return stroke' of l' the'shearing key, the bar is depressedby the spring 126vr and the shoulder 125 v on the bar engages a pivoted arm 130 which carries a block 131 normally engaging alug 132 on adental clutch coll`ar133- The 'with'-A drawalof the block by thedepressioiiV of thisv arm freesA the clutchlcollar and there-v upon a spring l35facting on the shipper' lever'136 throws 'the clut'chcollar into engagement with the matingmember l137 jon` 150 on a shaft`151- which carries a'pulley -the hub of the continuously rotating gear 139 loose on the shaft 140. This gear 139 is continuously rotated by any suitable. As shownitnmeshes with a' pinion 152 belted to apul'ley 153 onthe main clutch shaft 41. i When the dental clutch just described goes' into engagement the shaft 140 makes one rotation. At the end of the Vrotationvthe lug 132 acting on the beveled face 143 of the block 131 withdraws the clutch member 133 12 Vthrust on thearm 130 in this action'is refrom engagement, restoring they parts. l-'The ceived by thestationary bracket'plate138.

In setting the clutch as above described',V

when the shipper lever 135 shifts the clutch collar, a bracket Von the shipper lever engages a pin` 146 on the depending "flink 124 and thereby swings it against the action ofthe spring 147totclear the depressed arm 130,v and thereupon the`spring1i49 returnsthat arm to normal "position,=bringing thel iid I block 131 into position toengage the clutch' lug- 132 asabove described.

It will be seen from the abovedescription that whenever the shearing key 'is op-v erated a small sectionis s hearedout ofthe embossed strip, and then, as the plunger mechanism, die head and shearing lever: are being restored to normal position the shearing lever, through tliemechanism last described, effects the engagement of the dental clutch: to cause ya single rotation to the normally kidle shaft 140. This through mechanism which will now-be described, operates to shift the embossed and sheared Vstrip from its position within the die head toward, ther right of the machine.

The single rotation shaft 140, above mentioned is mounted in a U-'shaped frame casting Figs. 2,l 19 and. 2 0. Pinned on this shaft areitwo cams 161 and 162. The cam '161vc0acts with a roller 164 onyalink'165 son of its suddenly/.increasing face 169,V which, acting on the roller 164,. carries the plate 168 to its extreme left hand position.'`

Themas a portion of the cam ofk decreasing radius coactswith the roller 164, a spring 170., swings the lever 166 towardY the right and` thus shoves the plate 168.- in that directin. The plate 168I is pi-voted 'at 169 toa sliding bary 173 which-occupies a yhorizon-tal slideway 174y in the stationary frame rail 16.

Aspring 175 on the sliding bar'1`73' bears against thestationary rail 16 and forces the plate against the Vmating stationary frame=` rail 17. This makes a frictional drag on the pivot of. the plate so that whenv the plate moves toward the left in its initial positioning, the link 167 drawing itf rocks it upwardly a slight distance until the roller 177 carried by the plate engages the top of the stationary rail 17. Now, when the spring 170 acts to shove the plate 168 toward theright theV reverse rocking takes place until.- the roller 178 on the plate engagesthe rail, 17.'. This swings the nose 179V of. the plate downwardly so that it digs intothe section of the strip which was cut off by; the shearingl dies( Then as the spring170i continuesl to move the plate 168 toward the right the engaged-,strip isshoved with it into the pass ofthe delivery rolls 180.

The delivery Yrolls 180, Figs. 1, 2, 7 and 8- are continuously rotating quite "rapidly, and operate as soon as' they receive-the embossed strip 182, Fig. 2, toy force it through the roll* pass and deliver it intothe stationary T rail shaft,

192. These rolls, it will be understood, v no t only feed the stri-p but bend inwardly the edge flanges thereof, that is to say, they transform it from the parallel-,edged shape shown in section at 92 in Fig. 4 into the shapje shown at 182 in Fig. 22, wherein the end of which is one of the delivery rolls 180.

The other delivery roll 180 is geared with this roll to rotate at the same speed and op;-

posite Vdirection byintermeshing gears, ofV

which one is shown at in Fig. 2.

lVhile the cam 161 on the shaft 140 wasy acting, as above described, to shove the embossedk strip toward the right and into the pass of the delivery rolls, the cam 162 was acting to shove toward these delivery rolls the slide mechanism to engage the delivered strip,.- As shown, this cam 162 acts between two rollers 200 and 201 on a link 202 connected to a lever 203, the vupper end off which is connected by a link 204 to the ,sliding mechanisrn 205, which carries at its upper end,v a

pivoted hook member 206 adapted to engage the delivered strip. The cam 162'isvheartshaped and formed. to substantially contact atall times'wi-th each rollerf200 and 201,5'

4es, i

As it starts to rotate, its increasing radius acting on the roller 200 shifts the` slide mechanism toward the left untill the hook' member 206 thereon, by mechanism hereinafter-V described is in position to engage the delivered strip at-its; left hand end. Then as the portion of the cam` of decreasing radius coact's with the roller 200, the correspondingly increased. portion, bearing'against the roll v I 201, shoves the slide mechanism toward .the

right rocking the hook andi carrying with it the delivered strip and shoving it 'onto the receiving blanket 210. i

The blanket as shown in Fig. 23 comprises a sheetl metal' plate having` longitudinalfrows of round `buttons' 211 stamped from itl soiy asrto be Separatedfromit at their edges,v

while interrne'diately the buttons are ,con-I nected to the plate'and are further connected with each other by raised corrugations 212.

A plateis thus provided which makes a continuous support for the embossed strip 182 and at thek same timehas overhanging-shou-lL ders beneath which the curved in edges-183#-l` may extend. Such blanket is covered. in

patents toV Clifton Chisholm, B. J. YCraig and myself, Numbered 1,438,580, 1,438i'582f and 1,438,584 respectively, already mentioned.

Theblanket 21.0 described is mountedl on a suitable drum-likeform. As shownfin F i'g. I

$10,' 22.0 indicates a` segmental'drum on aV shaft 221. This drum is providedv with T- rails 222. The eXt-reme'edges of the blanket are rolled inwardly as shown at 215land216.

, One of these rolledy ribs is adapted to extend 192 which carries the delivered-strip, The

shaft 221 which carries this drumis mounted` in suitable brackets 230 and 231-securedto a.

suitable frame casting'234 lwhich isI secured to the main frame of the embossing machine and' carries not only the drumV described but H the slide mechanism 'which I will nowy de scribe. y

The slide mechanism referred to as205 includes a slide 210fslidable ona horizontal o yrod 241 andhavinr .ears 242. by which it is pivotally connectiedtov the link 204 leading from the cam operated lever 203. The slide 240has .a iattopplate 244 on which restsv a transversely extending .flat rocking bar .250. Carr ing a pin 251 dependinginto a notch 252 1n the top plate of the slide.

YThe transverse bar referred to is housed within a'recess- 255 in the lower face of a standard 256 which is slidable upon theY frame rod 257 and the frame plate 258. This standard' carries the vertical rock shaft 260, which at its lower end is pinned tothe rocking bar 250 and at its upper end adjustably but tightly carries the hook 206V.

As the slide 240 moves toward the left under the influence of the cam 1625 the right hand wall of the notch 252 (left handV in Figs. 11, 15, 16 and 17) engages the pin 251 depending from the rocking bar 250; and thus carries the rocking bar,fstandard and hook toward'the left until lthe point of the hook is beyond the left hand end of the delivered strip. i o

To carry the strip'from the delivery rolls into position so that'thempoint of the hook in its left hand position will be beyond it,

I provide a horizontally sliding hook 270, Figs. 7 and 24,'whiclnextends freely through the pass of the roll 180y andlhas its right h and portion 273 guided in a slideway inthe 'horizontally' stationary member274 which carries the rail 192,;for supporting thestrip. This rail -is slotted ,horizontally at 276Y to receive the hook'270. This hook member is Pintada? its right 5.2.1991 nl@ leise-.2.71 u

A and onto the'blanket.

which ,isl intermediatelyi pivoted to a link 27 2 andfdepends below its pivotfinto the path of a lug 275 on thevforward edge ofthe top plate of the slide y2110. Accordingly,as the slide mechanisml is carrying its hook 206 toward theleft it .is.also, through the intermediately pivoted 'lever 271, movingthe hook"'27 0 toward the right, thus drawing the iinished strip onto the rail 192, as shown in Fig. 24. 'lhus, as the slide mechanism reaches its 4left` handv position the jpoint.. of thehook 206 is .beyond theleft hand end of the delivered strip. l f 2 ,Y

. The hook is adjustable on the shaft 260 so that when it rocks inwardly to-its limit as hereinafter described,it overhangs the ejnd of thegembossed strip but it` does notrengage the supporting raili 192V behind it and will-v not subsequently yengage theblanket.

The adjustment ofthehook plate 206 with'A reference .to thevrod 260` isreadily effected by looselyjournaling the hookplate on the rod above a collar 282l pinnedlto the shaft.

'Suitable set screws 283 pass through arcuate slots 284 inthe hookplateand thus clamp it in place for thev desired adjustment, after which theparts are jammed by a nut 2.85 screwing onto the to'p of the 'shaft 260. s

j As hereinafterr explained, 'the hook 206 stands lnormally swung to the iront away fromfthe embossed strn When themove- Vment to the left begins the notch 252 catches up tothe pin 251.jasheretofore explained.

"Thereafter, during the; travel of the slide mechanism toward theleft the latching bolt 290` which slidably occupies the notch 291 in the rocking bar 250 is released as hereinafter explainedand moves downwardly underthe i, niuence of; the ,spring-292" into the Anotch '7252.` Itvwill be noticed thatthis notch 'isenlargedy at this point 296 so that there is'play 'of the lower end of the latching bolt in the notch. This is the normal conditionas the slide mechanism moves toward the left.` It

comes to rest with the hook' 206 beyondbut in frontof the left hand'edge ofthe embossed strip. Now'on the return movement the first thing that takes place is for the slide -240to ytake uptheslack'between the left hand or trailing edge of the slot 252 and jthe latchingfbolt 290and rock the rocking ban-until `it is` stopped. byv abuttin"g g"thek pin 280, the partsthus coming Ainto the position shownxin Fig. 16. 'The parts remain in this condition duringrthe right hand-movement of the slide mechanismiuntil the strip is drawn onto theblanket,y it being understood that one of the rows ofblanket buttons2i1`1 is lheld vin alignment with the railfy 192' so that as the. slide mechanism moves'toward the right under'the 'iniiuence of thecam162 the engaged stripk iSv dIfWB @193g the Islide :Vi/'hen the embossed strip reaches its final pgs/,ities 9p. the Q1-estates sheimip'figs- `and 11 its far end engages a bell crank v300,

which is rocked thereby and thus moves downward-ly the horizontal plate 302, this platev having a parallel-rulerk connection' with the .stationary `plate 303 by means of the portion 304 ofthe bell crank and a parallel and equal-length link 305. This plate .reinains'in 'its lowered position until leventually released and returned by a spring 306. This downward movement of the plate 302 causes', itto engage a roller 310 onfthe free 'end of a lever v311, the otherend of which is connected to the latchingbolt 290. This 1 resultsin raising the bolt vand lthereby tem- Vpor-arily unlocking the hook carriage from theslide. As soon as this takes place a slightY further movement toward the" right of the 'slide 240 brings the pinY 246 vagainst 'the step 247' as shown Fig-l 17, and therefore thejconti-nued movement of the slide and carriage allows the hook to swing forwardly away fromr the embossed strip,y and the rest of such movement ofthe -slide mechanism ifsidl'e. Y

By the means describechl am enabled to make the travel of theslide mechanism 'suiiicient to shove the shortest line onto the blanket; at Vthe saine time L irrespective of the length of the line, the q ook swings out Vposition' perf-'erm the'stopp-ing and releasing function heretofore described". y'This vmanual positioning 'of 'the stop 300 is 'ef- 'fected asfollflfows:

Referring to Figs. 1,x 2 and l8, it willl be seen that the 'stoppingbell'` crank 300, the movable plate v302 and the nermfally stationary plate 303 are al'l carried by a slidable carriage 320, this standard'being slid- 'ably 'mounted on the stationary plate '258 and' also on stationary rod 321 parallel therewith. A- .linkI A323 connects this carr-igage '320 with a man'nally lever 3 24 v'fhichA is p1voted at '325iy and. car-ries nearv its f'lele end up 32e engaging teeth on a sta-tiene@ segr-'rient '327'. i The elasticity of the lever 324 ifs sufficientto allow 'the lip to 'slide over when itis desired to move the stop carriage toward the, left. I-'t will then remain in this set position until: the lever 324 is slightly raised and swung back'manually to- Eyardthe left into some"'de'sired new posis'- heretofore alhi'd-ed to', the 'druni 220 which 'carries 'the blanket is normally locked into' position, but following the yplacing of an` embossed strip on theL blanket, 'the blanket is y'automatically given a partial rotation suicient to bring a new row of strip' yholding buttons 211 into registration with the strip rail 192. The mechanism for effectingthis will now loe/described with parblanket caused by this corrugationf is utilized Vto index the blanket and maintain y v'pjroper registration with the external strip holding rail'. This' featureis claimed'inthe application of Clifton Chisholm above mentioned. l

Figs. 12, 13 and 14 show at 340 a bevel nosed4 snu'bbing Apin pressed ltoward the blanket 210 by 4a spring 341, thisl pinand spring being mounted in a stationary (thoughV adjustable) bracketf3-42 which is Aloose on the drum shaft 221. The bevel nose of `this. pin engages in the rearwardly facing groove caused by the corrugation 212 of the blanket and by vreason of its beveled face and the inclination of the walls of the groove accurately centers theblanket. This snubbing` pin forms a lock of sufficient force not only to accurately center the bracket but to hold it normally in registration. l/V'hen, however, the. drum is given a partial rotation to present a new row of buttons the blanket simply snubs over the pin which is thereby cammed inwardly against its spring 341.

To cause the point vof the snubbing pin 340. to. be accurately in position with refer- `ence to the external rail 192.1 make the ybrz'icket 342 adjustable within slight limits. I

effect this by making a notch 35.0 in a downwardly ext-ending leg 345 ofthe bracket, and-in .this notch I mount an eccentric 3F51 on a short shaft 353 which is jo-urnaled in the `adjacent bracket 230 in which. the drum shaft 221 is journale'd. A screw driver notch 355 in the end of this shaft 353, provides .means for turning it and a lock "nut 351.6 it in accurate position.

To'. turn the drum step, .step- .automatically I provide'a disk-like collar 360 pinned to vthe shaft, andA cooperating with this is a roller 361 mounted between it and an abutment block 362 carried between and secured to plates` 363and 364 which are loose on 'the shaft. The face` 365 .of the abutmentblo'ck Vadjacent the `collar 36.0-` is. inclined downwardly toward thatcoll'ar andthe roller is. pressed toward they reted peling thus.

provided by a spring 367. The roller thus cordingly one ofcthose plates may `furnish means to give the desired partial rotation j n l l y 4portion ofthe plate 363 and `furnishing to the drum.

lI extend the plate 363 toward the.Y front.

where itl overlies and rests ona bell' crank 373 with a bell crank 372. The endyporvtion of the link is slotted at 378 about `a The spring an-` pin 379 on thebell crank. c hored to the link and the pin* normally maintains the pin against the left handV end of the slot and the bell crank Vagainst'the stop pin 374. This bell crank 372 carriesat 'its free end a pivoted cam dog 375 shown in Figs. 8 and 9. This dog has a rearward- `ly extending lip 376 which oyerhangs the substantially horizontal arm 377 of the bell crank 372 and supports the dog in position so that it extends diagonally 'above and belowV the path of a pin378 project ing rearwardly from the bearing portion of the slide 240. Now-when the slide mech- 'anism heretofore described 'is jmoving toward the rightto carry the embossed strip onto the blanket, the pin 378 engages beneath the cam dogf 375 and 'lifts'it idly and travels beyond it. On the return movement of the slide mechanism this pin 37 Sjengages the inclined top surface of the vcam dog137 5 and cams it and therbell crank 'arm 377 downwardly 'as the slide mechanism travels toward the left. This pulls onthe link 371, rocking the bell crank 370, raisingthe plate 363, and thereby rocking the drum to bring .and its connected parts to normalposition 'when the pin 373 clears the cam dog 375.

This restores these parts to normal position ready for another operation subsequent to the delivery of the next strip.

The movement of the drum', inv the operation described is accuratelylimited, preventing any overthrow by momentum, byxlneans of a pair of'set screws 385, Figs," 18,' 132- and 14, which engagea pin`386 carried by the plate 363. For convenience I have mounted these set screws in the depending leg 4 345 of the normally stationary standard 342.

As it is sometimes` desired to skip one or more lines on the blanket, I provide a manual device for rotatingthe drum, which may also be availed of to set theblanket originally to bring the desired` region .thereof into `receiving position.` This manual mechanism comprises simply ahand lever 390 projecting"forwardlywfrom the upper means for rocking it as desired.

To allow the drum to be turned backwardly'manually, I provide a releasing lever depressingfthe forward `end of this lever `the roller may be raised' tofunclutched position, ythereby freeing the vdrum and =allowing itI to be' turned byhand'as desi-red backwardly, as wellas forwardly,the snubbing. ypin springing into "fthe` successive groove as the blanket travels, and stopping it accurately in any registeringv position in which it may be left. Y 'v Y To enable'the blanket to be readilyplaced on .the drum, I provide fmeans for locking the snubbing pin 340j inwardly in idle posi- .tion. This means 'isy illustrated particularly in Figs. 13 and`14'and comprises ya plate -400 pivoted to the horizontal" arm vof the bracket'342 and normally held in'its upward position byia spring l401. This'plate fhasfan tending idly# into this opening isa pin .405

carried the snubbingpin 340. 'The open- *ingfi'sofsufticient sizeso that -inY the ordinary operation the pi1r405' moves' -idly in the. opening. When, however,'fthe plate 400 isrocked downwardly as maybe readily done 'manually by the Voperator engaging Vwith' his elinger the turnedover end 407 =of 'the plate), the inclined wall '403'engages the pin405 and withdraws thesnubbing piny into idle' position. It remains fin this yposition by reason of the1spring 341 forcving thepin 405 againstl the portion 408 of the opening'wall, which inclines slightly Y away'from the center.y The parts may be readily restored-whenever desired by a slight upward pressure on the lip 407.4 y

It is sometimes desirable/to deliver the embossed strip from the embossing-'machine onto the blanketvmanually. To effectl this readily without interfering with the am toina'tic operation described, I providev a handl wheel 410 Von theforward en do'f the shaft 140. This wheel normally `rotatesidly AWihenelver the: shaft` 140-1rotates."' It furnishes "means, however, `wihfereby this'shaft vmay berotated byhand whenever desired and thuscarry ont the' samefoperatio'nsas heretofore described when the4v dental clutch (shown in Figs 3,` 19-and 20) Visengaged and this shaft rotatedby means offthe continuously rotating gear 139. fh To prevent the dental clutch, controlling the automatic operation, from going into engagement duringthe lhand operation, I proend of the lever 122 (Fig. 3).

the upper end of the link 13.6 a 'link 415 which leads` forwardly and has its free end f portion supported .and guided by a stationary stirrup 416. Ordinarily this link 415 plays idly through the stirrup. The link, however, is provided with a notch 417 at its upper edge and a lip 41,8 on its forward end. When thevlink isdrawn forwardly 4by this lip and lifted, its notch embraces thestirrup plateV at the top of theslot therein and thus holds-the link elevated by friction, and this holds back-y the movable clutch member 13.3, enabling the hand operation by the hand wheel 410 las longv as desired. A. suflicient downwardV pressure, however, on the lip 418 releases this lock-out mechanism whenever desired.

To enable the delivery mechanism to operate without requiring the operation ofthe shearing mechanism so that the drum may be indexed idly (as fory instance when oomposing double-space matter) I provide an extra key-450 at the side of the key-board (Fig.` 1) which has a shank extending downwardly and connecting with the forward The connection of the lever 122 with the shearing key is vby a pin and slot as shown in Fig. 3, so that when the lever 122. is operated by the key 45,0, the. shearing key isy not operated thereby. VThis allows the dental clutch controlling the automatic indexing to be independently initiated whenever desired.

The indexing by the key 450 just described will ordinarily be done immediately following the deliveryv of a strip onto the blanket and before the subsequent strip is embossed. If, however, the operator delays the idle indexing until after lhe has embossed the subsequent line ora material portion of it, the toe 17 9 of the shoving plate 168 will stick in such embossed line or portion which it cannot feed, the spring 170 yielding idly. To prevent damagel to the machine in case such sticking occurs while the plate 168 is overlapping the embossing o-pening 18 I provide the safety mechanism shown in Fie-gs. 2, 4 and 5. This mechanism comprises a slotted link 420 loosely connected to they lever 166, which operates'the plate `168, and pivoted at its other end to the lower end of a rock lever 421.. The upper end 42.2 of this lever-extends adjacent to a col-lar 428013 the clutchv operating red 38. Grdflarily this leverl portiqn, 422 is held out f registratian with the 0011er by a spring 424 as.: shown in Figs.-

and; NOW if the plate 168 Should Stand in, regst1fation-wth-the opening, 118, thenthe lever 166.v will pulltlle rod 420 to- Ward the left Fig.- 2, rockin-atlas lever sothat its apparenti 422 stands front of, the collar 423.- ln isuclicend n, when the rocking plunger. 30. en the da head, rises from engagement with the key lever and tends, through the bale, link and bell crank mechanism heretofore described, to .with-- draw the clutch rod, such operation is noneffective, because the clutch rod is locked. Therefore the lower end of the bell crank 3.7 simply compresses a s-ti spring 425 Which, as shown in Fig. 4, positions a slidablehead 426 into which the lowerv end of the bell crank 37" extends. Normally this 75 spring presses this head against ka shoulder on therod and the head acts unitarily with the rod, to withdraw it when the bell crank is operated, butl Vunder the condition just described the spring forms a safety device prer venting straining the. parts.

My prior application referredto, shows a mechanism for loading delivered embossed strips onto a flat address plate. The present mechanism has been designed so that a: somewhat similar device for holding a flat plate may be substituted for the drum y220. To enable this to be readily effected, I mount the drum shaft 221 in upwardly opening slots in the two standards, 230 and 281, and I, cover the shaft at these bearings by movable retaining plates 46.0 adapted tov release it.

As shown in Fig. 7, each retaining plate 46()` has a notch in-its rear edge extending beneath a screw 461 and .has a slot 462 through which extends a clamp screw 463, which when loosened allows the plate to be slid forwardly to idle position. The sliding or removal of these plates enables the shaft, with the drum and operating mechanism mounted on the shaft, to be readily removed from the standardsv and other mechanism substituted.

It will now be understood, from the given description, that I have provided a mechanism adapted to be coupled with an embossing machine which produces embossed printing strips, and feedsuch strips onto a suitable; receiving blanket, and that the mechanism is arranged to operate entirely automatically consequent upon the operation of the key which shears olf vthe embossed line. Ags soon as such key is operated, the delivery mechanism described is initiated and proceeds with its function independently of the operator, who may go on with the embossing of a subsequent line. The complete delivery ofl the embossed line, while sufficiently deliberate to operate smoothly, is effected well in advance of the time it will take the operator to emboss a new line.l Accordingly, his embossing oper-ation proceeds without delay, and substantially as; soon as he has embossed Suie1it lines to constitute 125 a. page ferm, the same are proper-1y assembled @n the blanket, and althat isilecessary is to release theblanket from the drum and iti-s; ready foruse-in a suitable printing chinethis-mechanism is normally 1530
